.br
.SH DESCRIPTION
This manual page briefly documents the

is a helper utility that takes a list of map tiles from stdin and sends the requests to a rendering daemon
.PP
.SH OPTIONS
This program follows the usual GNU command line syntax, with long
options starting with two dashes (`-').
A summary of options is included below.
.TP
\fB\-a\fR|\-\-all
Render all tiles in given zoom level range instead of reading from STDIN.
.TP
\fB\-f\fR|\-\-force
Render tiles even if they seem current.
.TP
\fB\-m\fR|\-\-map=MAP
Render tiles in this map (defaults to 'default').
.TP
\fB\-l\fR|\-\-max-load=LOAD
Sleep if load is this high (defaults to 16).
.TP
\fB\-s\fR|\-\-socket=SOCKET
Unix domain socket name for contacting renderd.
.TP
\fB\-n\fR|\-\-num-threads=N
The number of parallel request threads (default 1).
.TP
\fB\-t\fR|\-\-tile-dir
Tile cache directory (defaults to '/var/cache/renderd/tiles').
.TP
\fB\-z\fR|\-\-min-zoom=ZOOM
Filter input to only render tiles greater or equal to this zoom level (default is 0).
.TP
\fB\-Z\fR|\-\-max-zoom=ZOOM
Filter input to only render tiles less than or equal to this zoom level (default is 20).
.PP
If you are using --all, you can restrict the tile range by adding these options:
.br
  -x, --min-x=X        minimum X tile coordinate
.br
  -X, --max-x=X        maximum X tile coordinate
.br
  -y, --min-y=Y        minimum Y tile coordinate
.br
  -Y, --max-y=Y        maximum Y tile coordinate
.PP
Without --all, send a list of tiles to be rendered from STDIN in the format:
.br
  X Y Z
.br
e.g.
.br
  0 0 1
.br
  0 1 1
.br
  1 0 1
.br
  1 1 1
.br
The above would cause all 4 tiles at zoom 1 to be rendered
